Abstract: 1,085,325. Signal lamps. SENDLINGER OPTISCHE GLASWERKE G.m.b.H. Oct. 16, 1964 [Oct. 18, 1963; March 19, 1964], No. 42420/64. Heading F4R. Screening means are provided in a signal lamp between the light source and the front of the lens to intercept sunlight entering the lamp and thereby prevent the formation of phantom signals. Sunlight capable of producing phantom signals can only enter the lamp through a limited solid angle, and the screening means is arranged to intercept only light entering the lamp within this angle. In one embodiment, Fig. 2, a diaphragm plate 12 is placed in the focal plane of the lens 11 and has an opaque region 12<SP>1</SP> to intercept the sunlight. The opaque region may be made reflective on the side facing the source 15 so that signal light reaching the region is returned to the lamp reflector 16, which is of parabolic, elliptical or spherical form. The lamp may have a number of smaller lenses or a lens of annular configuration in place of the single lens 11, in which case the diaphragm plate is povided with a number smaller opaque regions ror an annular opaque region respectively. In an alternative embodiment (Figs. 7-10, not shown) the diaphragm plate is omitted and the inner surface of the lens is formed with a series of horizontal prisms. Sunlight entering the smooth outer surface (52) of the lens is internally reflected at the inner face (53) of a prism and directed on to the screened lower face (54). The angle of the prisms may vary over the surface of the lens, and the inner faces of the prisms may be curved. The lens or the diaphragm plate may be coloured.

Title: Releasable coupling for liquefied gas conduits
Inventor: SNOWMAN JOHN WASHINGTON
IPC: F16L37/40
Filed: 1960-12-09
Abstract: 919,230. Pipe couplings. BRITISH OXYGEN CO. Ltd. Dec. 11, 1961 [Dec. 9,1960], No. 42497/60. Class 99(1). In a releasable coupling 10 for liquefied gas conduits of the kind in which at least one member forming part of the coupling is required to slide upon and relative to another member forming part of the coupling, both when the coupling is released after use and when it is re-engaged for further use, to prevent ice formation internally of the coupling, a bleed of gas is deliberately provided from the liquid-carrying bore of the coupling to a clearance space 48 between the relatively slidable members so that the space is purged by the gas. As shown, the coupling comprises a tubular member 12 provided with a spring-loaded check valve 75 which is opened by engagement of the member with a fixed coupling member 23, the two members being connected by a bayonet joint the pins 28 of which are fixed in a sleeve 26; the latter also has pins 31 which engage in cam grooves 32 formed in a sleeve 33 mounted on the member 12, a compression spring 34 urging the sleeve 33 rearwardly of the member 12 and against a shoulder 35. Springs 37, 38 are interposedbetween a flange 42 of the sleeve 33 and the sleeve 26 to bias these sleeves to the uncoupled position thereof. A sleeve 40 serving as a rotatable handgrip is secured by an internal flange 41 thereof to the flange 42. In operation, the pins 28 of the sleeve 26 are engaged in the bayonet slots of the member 23 and the sleeve 40 is rotated to cause the sleeve 33 to rotate relatively to the member 12 and the stationary sleeve 26 and to move forwardly together with the member 12 until the latter is in liquid-tight sealing contact with the member 23. A bleed passage 46, adjustable by a screw 49 to regulate the effective size thereof, connects the bore 13 of the member 12 with a clearance space 48 between that member and the sleeve 33 so that the space is purged by a seepage of the gas which is flowing in liquid state through the coupling; an additional bleed 70 passage is provided in the member 12. Resilent sliding seals 55, 60 and 63 prevent escape of gas externally of the coupling.
Patent GB-1341543-A (GB)
IPC: H01Q3/42
Filed: 1972-09-14
Abstract: 1341543 Aerials INTERNATIONAL STANDARD ELECTRIC CORP 14 Sept 1972 [17 Sept 1971] 42624/72 Heading H4A An aerial scanning arrangement comprises an array of aerial elements each of which is associated with a mixing means for coupling signals of respective frequencies (f 0 +f s ), (f 0 -f s ), where f 0  is fixed, and f s  is a variable steering frequency. A phase shift means has a respective terminal associated with each mixing means and provides progressive phase shifts in one of said coupled signals. A first means receives signals at the frequencies f 0 , f s , and couples one of the signals of frequencies (f 0 +f s ), (f 0 -f s ) to or from said phase shift means, and couples the other to the mixing means. In a first embodiment, a linear array of monopoles or dipoles is provided with scanning in azimuth. The phase shift means is a delay line which is fed at one end, and is tapped at regular intervals for connection to successive mixing means (Fig. 1A not shown). In a second embodiment, a twodimensional aerial array is made up of rows and columns of radiators 19, Fig. 2A, each radiator being coupled to a respective mixer 18. A secondary delay line 16 is associated with each column of radiators, taps being taken therefrom at regular intervals to successive radiators in said column. A primary delay line 6 is tapped at regular intervals to feed successive secondary delay lines 16. A signal of fixed frequency f 0  is generated by a prime oscillator 1, and a signal of variable frequency f s  is generated by a steering oscillator 2, and both signals are fed as inputs to a mixer 3. An output of frequency (f 0 +f s ) from the mixer 3 is fed to one input of each mixer 18 and, in the transmit mode, the other output of frequency (f 0 -f s ) from the mixer 3 is fed via a switch SW to the input of the delay line 6. The output from each mixer 18 to the associated radiator 19 is of frequency 2f 0 , and it has a relative phase made up of an azimuthal component which is determined by the spacing between taps on the delay line 6, and an elevation component which is determined by the spacing between taps on the delay lines 16. The spacing between taps on the delay line 6 is considerably more than the spacing between taps on the delay lines 16 and, consequently, as the frequency f s  is raised the beam from the array is rapidly scanned in azimuth, is then succeeded by another beam at somewhat higher elevation, which is likewise rapidly scanned in azimuth, and so on. A raster like scanning pattern is thus produced. In the receive mode, the switch SW is operated so that the end of the delay line is connected to one input of a mixer 13. Said mixer also receives an input of frequency f s  from the oscillator 2, and it provides an output of frequency f 0  for receiving equipment.

In a photographic roll-film camera Fig.1 in which film is advanced from a film supply magazine 33 to a film take-up spindle 3 mounted in the camera and then the exposed film is rewound back into the supply magazine, a single film wind lever 1 is used to wind and to rewind the film, selector slide button 38 being provided to enable either the film take-up spindle or the film supply magazine spool to be connected to the film wind lever. During the advance of the film, the takeup spindle 3 is engaged by the clutch member 12 so that the film wind lever 1 drives the spindle and the rewind shaft 34 is disengaged from the magazine spool 37. A system of pawl levers 15 and 21 carrying pawl teeth 17 and 25 operating in conjunction with metering sprocket 66 and recessed wheel 69 checks the advance of the film after the correct length for the next exposure has been wound on. The pawls are freed by the action of lever 82 when the shutter release button 78 is pressed. Operation of the film wind lever 1 cocks the shutter by means of lug, 72 and levers 73 and 77. When the film is to be rewound, the selector slide button 38 is slid down and the lug 87 cams the slide bar 89 to the left to lift clutch member 12 free of the take-up spindle and at the same time to disengage the pawls 17, 25 and 27 by the action of projection 96 thus freeing the film wind lever. At the same time the rewind shaft 34 is engaged with the film magazine spool 37 and the film rewind pinion 59 is meshed with the gear 55 enabling the film to be rewound. In a further embodiment (not shown), the selector slide carrying the slide button 38 is associated with a locking device so that the camera back cannot be opened during film advance.
